Title: Magneto-optical recording and reproducing device
Inventor: MIYAKE TOMOYUKI
IPC: G11B21/16
Filed: 1991-12-27
Abstract: PURPOSE:To enhance the reliability at the time of writing and reading by detecting the pressing to a magneto-optical recording medium by an element and driving a mounting base for a suspension on a prescribed direction, thereby maintaining the specified pressing. CONSTITUTION:The pressing of a magnetic head 8 to the recording medium is detected from the output voltage of a piezoelectric element 10 and the suspension mounting base 11 is vertically moved to maintain the specified pressing. An actuator mechanism is adopted at this time and an objective lens of the optical recording and reproducing device is made to follow up the surface waving of the optical recording medium 1. The mounting base 11 is mounted with a coil 15 for the actuator by an adhesive and is connected to a supporting base 12 by a leaf spring 18. A yoke 16 for the actuator and a magnet 17 for the actuator on one side of the yoke 16 are so mounted as to hold a part A of the coil 15. Thus, servo is applied by passing a current to the coil 15 in accordance with the output from the element 10 by a fluctuation in pressing. The mounting base 11 is then moved and the head 8 and the medium 1 are constantly pressed.
